Redux Basics: Store, Actions, Reducers
Redux is a state management library for JavaScript applications. In this lesson, we will learn about three key Redux concepts: store, actions, and reducers.
Synopsis
In Redux, the application's state is centralized in a single place: the store. To update the state, actions are used, which are objects that describe the modifications to be made. Reducers are functions that specify how the state changes in response to an action.
- Store: It is the object that holds the application's state.
- Actions: These are objects that describe the changes that should be made to the state.
- Reducers: These are functions that take the current state and an action, and return a new state.
Purpose
Redux helps manage the state of complex applications predictably and scalably. With the three key concepts, we can control the data flow and track state modifications clearly and simply.
